Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This phase I trial studies the side effects and best dose of CB-5339 in treating patients with solid tumors that has spread to other places in the body (advanced) or lymphomas. CB-5339 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
